Cet. 25, 1932. -H, E. HERR L884p684 FLYER FOR SPINNING MACHINES AND THE LIKE Filed Aug. 7. 1951 Patented Oct. 25, 1932 UNITED STATES PATENT OFFICE HARVEY E. OF BUFFALO, NEW YORK, ASSIGNOR 'IO HERR MANUFACTUIRING COM- PANY, ING., OF BUFFALO, NEVI YORK, A CORPORATION 0F NEW YORK FLYER FOR SPINNING MACHINES AND THE LIKE Application filed August 7, 1931.

This invention relates to certain new and useful improvements in the flyers employed in connection with spinning machines and the like.

Its principal object is to provide the llyer with positive and effective means for preventing the flyer overrunning or continuing to revolve after the bobbin has come to rest, and thereby eliminate the many objections resulting from the overrunning of the flyer.

Another object of the invention is the provision of 'a flyer of this character having automatic braking or arresting means applied thereto which is designed to permit the normal free-running of the flyer but' which will positively arrest its turning at substantially the same time the bobbin is brought to rest.

A still further object is to provide a brakeequipped flyer which is simple, compact 'and inexpensive in construction, which is reliable in operation, and which is not liable to get out of' order.

In the accompanying drawing Figure lis a. fragmentary front view of a portion of a spinning machine showing my improved Vflyer applied thereto. Figure 2 is an enlarged top plan view of the fl er. Figure 3 is a bottom plan view there@ Figure et is a fragmentary vertical section taken substantially in the plane of line l---Lh Figure 2. Figure 5 is a perspective view of the braking element spring. Figure 6 is a similar view of the braking element. Figure 7 is 'a similar View of the wire base.

Similar characters of reference indicate corresponding parts throughout the several views.

This invention is applicable to spinning machines of any suitable and well known construction7 10 indicating the bobbin spindle and 11 the takeoff bobbin mounted thereon. The thread or yarn from the bobbin extends upwardly through the eyes of flyer wires 12, 13 mounted on a holder or flyer-body applied to the bobbin-spindle and indicated generally by the numeral 11i, and thence upwardly through a guide or centering eye 15 to a driven take-up spool (not shown). The bobbin shown is of the type used with flyers of the ec- Serial No. 555,705.

centric type and has a recess 16 in its top containing an inverted cup-like member 17 having an opening 18 therein arranged eccentric to the asis of the bobbin-spindle.

TWhile the flyer-body, which is revolvably mounted on the spindle 10, may be of any appropriate construction, that shown in the drawing, by way of example, is of the eccentric type and consists of an attaching sleeve or barrel 19 adapted for engagement with the tapered end of the spindle above the bobbin, a hub member or collar 2O fitted on the sleeve, and a base plate or spider 21 applied to the collar and to which the flyer wires 12, 13 are detachably connected. The sleeve 19 extends freely through the cup-opening 18 and ter min ates at its lower end in an eccentric flange 22 arranged to abut against the bottom of the top side of the cup-lil e member 17 in the operative position of the parts. As shown in Figure 2, the base plate has wire-retaining loops 23 formed therein which are adapted to receive the shanlrs of the flyer wires and applied to the collar 2O is a rotatable locking ring 2li having vertically-offset flanges 25 which overlap the bent inner ends of the wires and serve to deflect or spring such bent ends laterally to hold them against displacement in their retaining loops.

Applied to the flyer-body is a braking device which is adapted to frictionally contact with the adjoining portion of the bobbin 11 for arresting the rotation of the flyer relative to the latter and preventing its over-running the same. In the preferred construction of the braking device shown in the drawing, the same consists of a brake element in the form of a wire bail or loop 26 applied to the bottom side of the base plate 21 at one side of the flyer axis and pivoted at its inner end thereto to swing vertically into and out of friction al engagement with the hea-d or cap-plate 27 of the bobbin. This brake elementmaybebent up into any desired shape and its inner or free ends preferably terminate in hinge-pintles 28 which detachably engage loops 29 pressed directly from the base plate of the flyer. As shown in Figures 1 and 4, the brake element is disposed substantially radially of the flyer and may be made so as to counter-balance the flyer Wires l2, 13. ln order to yieldingly urge the brake element 26 into frictional contact with the bobbin-head 27,1 preferably employ a flat spring 30 Which is suitably attached to the underside of the base plate 21 and Whose free end or bearing portion 3l is bent downwardly away from said plate and rests against the top side of the bralringxelement adjacent .its hinged end. Thisspringis comparatively rlight and When the lbobbin is running at its normal speed, say 10,000 to 11,000 R. P. M., the centrifugal force urges the braking element upwardly against the resista-nce oll'ered by the spring-end 31, to a substantially Vhorizontal position against the underside of the base plate, Where it is clear and free of the bobbin and does not in any Way interfere with its normal operation. However, should the speed of the bobbin be lowered, as when stopping the machine, the braking element Will gradually be urged by its spring to a" downwardly, inclined position, until, at a predetermined speed of the bobbin, say about 4,000 R. P. M., it Will contact gently With the top face of the bobbinhead and the resulting friction between the rparts Will cause the flyer to be arrested With that -of the bobbin, the friction effect being increased as the speed of the bobbin is lowered.

By providing a braking device of this character, the flyer is positively and elfectually prevented from over-running the bobb'm, thereby eliminating the unvvinding of the i "thread fromthe bobbin and the resulting formation of objectionable kinliing .o'f the thread.
